SPRING-GRIPPING DEVICE.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed December 6, 1919. Serial No. 343,099.

To all whom it may concern:

Be it known that I, HARRY llisrror, a citizen of Ukrainia, residing at Lyons, county of \Vayne, and State of New York, have invented certain new and useful Improvements in Spring-Gripping Devices, of which the following is a specification.

This invention relates to a spring gripping device whereby a coiled tension spring which has become broken may be quickly put into service again without necessitating a machine of which such spring may form a part lying idle while a new spring is being obtained and fitted in place.

The invention has for an object to provide a simple and inexpensive device adapted to grip broken end of a coiled spring and secure it to its proper part or mechanism.

This invention is particularly useful in connection with those clothes pressing machines in which an upper presser member is adapted to be moved down against a lowerpresser member by power transmitted through a tension spring, although not necessarily limited to such use.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Figure l of the drawings is a perspective View of my improved spring gripping device.

Fig. 2 is a horizontal sectional view illus trating particularly the manner in which the device is placed in position on the spring this View being taken on the line 22 of Fig. 3.

Fig. 3 is a side elevation of the device showing it applied to a spring, connected to a foot lever such as is used in presses of the kind above referred to.

As here shown my improved device comprises a short rod 1 terminating at its upper end in a hook 2 and having integral with its lower end a pair of downwardly and outwardly inclined arms 3. Rotatably mounted on the rod 1 just above the point of juncture of the arms 3 is a collar 4: held against downward movement by these arms, and to which is fixed the upper end of a third downwardly, and outwardly inclined arm 5. The arms 3, as seen in plan view, extend at an angle of 120 to each other.

The arms 3 have vertical extensions 6 having at their lower ends the inwardly projecting, upturned hooks 7, the swinging arm 5 having a like vertical extension 8 ending in a like hook 9. Thees extensions are arranged to lie in. the surface of a common cylinder whose axis is co-incident with the axis of rod 1. Each of these extensions 6 is formed near its upper end with an inwardly projecting apertured offset 10 through which passes a rigid ring or band 11 which also passes through a like apertured offset 12 in the extension 8 this band passing loosely through the projection 12 although such loose fit is not essential in the projections 10.

In Fig. 3 of the drawings 1 have shown my device gripping the upper end of a spring 13 connected at its lower end to a foot lever 14. In connection with the clothes pressing machines above referred to it may be said that any breaking of the springs of such machines nearly always occurs near the upper end of the spring. To apply my improved device the short broken portion is removed, the hooks 7 and 9 are all engaged under the top loop of the spring, the arm 5 being swung adjacent one of the arms 3 while this is being done as indicated in broken lines in Fig. 2, and then the arm 5 is swung to the position shown in full lines where it is evenly spaced with respect to the fixed arms, the hook 9 on the end of this arm maintaining its engagement with the spring. The hook 2 is then connected to the required part and the spring is ready for operation.

It will be understood of course that the device will be made so that the radial spacing of the extensions will cause them to fit snugly or with compressive force over the spring when in place. The arm 5 may also have sufiicient frictional hold with the ring 11 to insure its staying in its proper position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is- 1. A device of the class described comprising a pair of fixed arms and a movable arm said fixed and movable arms presenting spring engaging devices spaced evenly from a common center, said movable arm being adapted to swing around the said center, and said fixed arms extending at an angle to one another.

2. A device of the class described co1nprising a pair or fixed arms and a movable arm said fixed and movable arms presenting spring engaging devices spaced evenly from a common center, said movable arm being adapted to swing around the said center, and said fixed arms extending at an angle to one another, and a ring engaging each of said arms, said movable arm being slidable on the said ring.

3. A device of the class described comprising a short rod length having a hook at its upper end, a pair or arms extending rigidly downwardly and outwardly from the said rod length, a third arm pivotally at taeh'ed to said rod length. at its upper end and extending downwardly and outwardly, a band with which each of said arms en gages, said third arm being slidable on the said band, and hooks carried by the said arms adapted to engage a loop of a coiled spring.

4. A device of the class described comprising a short rod length having a hook at its upper end, a pair or arms extending rig idly downwardly and outwardly from the said rod length, a third arm pivotally attached to said rod length at its upper end extending downwardly and outwardly, vertical extensions on all of the said arms provided on their lower ends with intnrned hooks, apertnred projections on the inner faces of said extensions, and a band passing through said apertures.

In testimony whereof 'I have all'ixed my signature.

HARRY BISHOP.
